This oil sample is not from a Dmax, but a Detroit Series 60. The engine has 200008 miles on it, and the oil had 13733 miles on it. This was the first run of Schaeffer 7000 15w40 synthetic blend CJ-4. The results show a very impressive add pack as part of the oil. According to Schaeffer, their 9000 5w40 full synthetic has the same add pack. I would have no problem putting this oil in a Dmax. I am going to stretch out the drain interval on the next run 3000 miles per their recommendation.
